Remove the Plain-Text Body from an Email

Demonstrates the Chilkat Email.RemovePlainTextAlternative method, which removes the plain-text body from the email if one exists. Other body representations, attachments, and related items remain unchanged. This example builds a message with both plain-text and HTML alternatives, then removes the plain text.

Background: This is the counterpart to RemoveHtmlAlternative. Removing the plain-text alternative leaves an HTML-only message. Note that dropping the plain-text fallback is generally discouraged for real mail — it hurts accessibility and can raise spam scores — but it is occasionally needed when a downstream system expects a single HTML representation.
